Thanks for the response.
     I have looked and compared the IBM 3494 using 3590E drives against
     StorageTek 9740 using 9840 drives.  And even though IBM has a faster
     drive (3590E) it looks technically (on paper) that StorageTek robotics
     will offset the IBM drive speed.  We would need two frames for IBM
     compared to single StorageTek frame. IBM has an average access time
     per frame around 65 seconds vs. StorageTek 18 second access time.
     Which means we would waste a lot of time getting tapes on the IBM
     library.

     Another concern I have is nobody can get IBM's 3590E drives until
     August (maybe) and what kind of bugs are they going to have.

       Master, I agree.  Especially with the release of the high capacity E
       series
       tape drives out now.

       Hi. Just one suggestion : I've seen so many people complaining about
       their
       StorageTek libraries on this list that I would suggest you to see
       for
       another options. Additional Magstar drives, for instance ...

       good luck !
